Answer: Neither co-linear nor co-planar
Step-by-step explanation:
The different Points are called co-linear if they are lying on same straight line.
While, they are called co-planar if they are lying on the same plane.
Since, By the diagram, S , T, Q and U are not co-linear because all are lying on different straight lines.
And Again by the diagram, they are not co-planar because they come in different plane.
Thus, fourth Option is correct.
Answer:
=
- 4
The conjugate of - 2 + i is - 2 - i, thus
- 2 + i + (- 2) - i
= - 2 + i - 2 - i ← collect like terms
= - 4 ← in the form a + bi with b = 0
